Question: Can we autodetect meaningful features.

Feature Engineering is an ad-hoc manual process that depends on domain knowledge, intuition, data exploration, and creativity. However, this process is dataset-dependent, time-consuming, tedious, subjective, and not a scalable solution.

Automated Feature Creation automatically generates features using a framework; these features can be filtered using Feature Selection to avoid feature explosion.

Below are some popular open-source libraries for automated feature engineering:
